There’s a very good reason why an upcoming mystery anime about a dog is collaborating with a sushi restaurant.

As part of a collaboration between Inu to Hasami wa Tsukaiyou and the chain restaurant Sushi Zanmai, people who buy a copy of the InuHasa light novels or manga at certain stores will receive a coupon good for one free piece of lean northern bluefin tuna sushi (honmaguro akami) at Sushi Zanmai’s Akihabara store.

In addition, there will be a kuji lottery in the store where you have a chance to win a figure of the heroine, Kirihime, or products signed by the author Shunsuke Sarai or Madoka’s voice actress, Kana Asumi. The campaign will run from June 29 to July 7.

If you’re wondering what InuHasa has to do with tuna, the character Madoka has a kitchen knife named “Maguro Eater” (“Tuna Eater”). You can see Madoka promoting the campaign with the Maguro Eater(?!) in the commercial below.

Inu to Hasami wa Tsukaiyou is centered around Madoka’s brother, Kazuhito, a bookworm who is shot by a robber and reborn as a dachshund owned by the sadistic author, Kirihime Natsuno. The anime starts airing on July 1, but you can see a trailer right now in our previous article.
